Definitions
- the invention relates to an actuating device for a shift sleeve in a change-speed gearbox, having a two-armed shift fork and at least one guide element for guiding the actuator in the axial direction of the shift sleeve and a driver element, which is suitable for engagement of an actuator.
- the shift fork here consists of a fork-shaped basic body made of sheet metal.
- the sleeve-shaped guide is welded to the shift fork.
- the driver element is connected to the unit consisting of shift fork and guide. The welding creates a strong bond between the individual components.
- the production cost is relatively high.
- the DE 199 27 321 A1 shows a shift fork made of plastic material. It has a basic body with two arms in U-shape and a driver for the fork. The main body, the two arms and a shaft, which is suitable for guiding, are made in one piece from plastic. In this case, the driver is formed by an integrated in the formation of the body insert. However, the plastic material used does not have the strength like a metal component.
- a shift fork which has a base body which has the switching arms for driving the shift sleeve and a shift rail, which is provided for storage and guidance in the transmission housing.
- the main body and the shift rail are each made in a stamping and pressing process and then joined together by laser welding. This also results in a relatively high production cost.
- the DE 100 32 163 A1 discloses an actuating device for a change-speed gearbox, which is designed as a composite part and has a made of a sprayable or castable material guide tube to which the shift fork made of metal and the driver are attached.
- the manufacturing cost of such an actuator is equally relatively high.
- the present invention is therefore based on the object, an actuating device for a shift sleeve of the type mentioned in such a way that the mentioned disadvantages are avoided.
- the device should thus both have a high component strength and be produced in a particularly economical manner.
- the solu tion of this object by the invention is characterized in that the shift fork, the at least one guide element and the driver element of the actuating device are formed integrally and from a single sheet metal part.
- the manufacturing effort is thereby significantly reduced, so that a particularly economical production of the device is possible.
- the one-piece composite also results in a high component rigidity. Since a metal sheet is used as the base material of the device, the component strength is likewise very high.
- the sheet metal part is preferably flat in the initial state and has a substantially constant sheet thickness.
- a particularly economical manufacture of the device is possible if one of the arms of the shift fork is formed by a punched out of the sheet metal part and bent out of the plane of the sheet metal part.
- At least one arm may taper from the base of the shift fork to the end of the arm; the taper is preferably carried out in the axial direction of the shift sleeve.
- a particularly simple production of the one arm is achieved if this is formed by twice bending the sheet metal part relative to the base of the shift fork.
- the remote from the base of the shift fork part of the arm can be arranged substantially perpendicular to the base.
- the other arm of the shift fork can be formed by a single turn of the sheet metal part relative to the base of the shift fork; Also this arm can be arranged substantially perpendicular to the base.
- a further development provides that two guide elements pointing in the axial direction of the shift sleeve and in opposite directions are formed from the sheet metal part. These may be formed as extending in the axial direction pins; the pins may have a rectangular or square cross-sectional shape.
- the actuating device is preferably used in motor vehicle manual transmissions.
- the actuator can be made of very few individual components.
- the joining processes in the manufacture of the device are reduced or they fall completely away. In particular, no welding or embossing is required to make the device.
- the complete manufacturing of the actuator is possible in a single machine tool (machining center), if it is equipped with appropriate tools.
- the tolerance chain is reduced, so that a higher component accuracy can be achieved with less effort.
- a joining together of different components is eliminated.
- Another advantage is that therefore an improved function of the device is to be expected, since the force curve is improved in the component due to a higher homogeneity of the part. Furthermore, lower deformations are to be expected in comparison with the previously known solutions, since the device can be made more stable or stronger. There are still lower voltage spikes in the material.
- an actuator 1 can be seen, with a sliding sleeve 2 can be actuated, d. H. with which the shift sleeve 2 can be moved in the axial direction A to perform a switching operation in a change-speed gearbox in a known manner.
- a functionally essential part of the actuator 1 is first the shift fork 5, which has two arms 3 and 4, which engage in an annular groove 12 on the circumference of the shift sleeve 2. For an axial displacement of the shift sleeve 2 with a corresponding movement of the shift fork 5 is possible.
- the actuating device 1 has at least one guide element, which is formed in the embodiment by the two elements 5 and 6. With these pin-shaped elements 5, 6, the actuating device 1 is mounted and guided in a gear housing, not shown.
- the driver element 8 can cooperate with an actuator.
- the actuator may be a part of a shift linkage or a differently shaped actuator with which a controlled movement in the axial direction A can be generated.
- the driver element 8 thus absorbs the switching force generated by the actuator.
- the actuating device 1 is in fact formed from a flat sheet metal, which has a flat contour in the initial state, ie before the beginning of sheet metal forming, and has a constant sheet thickness d.
- the embodiment of the one arm 4 of the shift fork 5 is particularly advantageous.
- the shift fork 5 has a base 9 which can be considered as a reference surface. From the area of the base 9 and the adjacent part of the other arm 3, a strip-shaped contour 13, s. Fig. 2, partially punched out, but the one end of this contour 13 remains materially connected to the base 9. The tongue released from the material of the base 9 is then bent out of the plane of the base 9, and indeed - as best seen in Fig. 1 - approximately at right angles to the base 9. As a result, the arm 4 is formed.
- the other arm 3 of the shift fork 5 consists of two sections 3 'and 3 ", both of which are each substantially straight, but are each bent at an angle relative to each other, so that the part 3' of the arm 3 is angled relative to the base 9 Also, the part 3 "of the arm 3 is angled relative to the part 3 'of the arm 3 (see Fig. 1).
- the ends 10 and 11 of the two arms 3 and 4 are arranged substantially perpendicular to the base 9, so that there is a switching jaw, which engages in the annular groove 12 of the shift sleeve 2.

Abstract
Description
Die Erfindung betrifft eine Betätigungsvorrichtung für eine Schaltmuffe in einem Zahnräderwechselgetriebe, mit einer zwei Arme aufweisenden Schaltgabel und mindestens einem Führungselement zum Führen der Betätigungsvorrichtung in Achsrichtung der Schaltmuffe sowie einem Mitnehmerelement, das zum Eingriff eines Betätigungsorgans geeignet ist.The invention relates to an actuating device for a shift sleeve in a change-speed gearbox, having a two-armed shift fork and at least one guide element for guiding the actuator in the axial direction of the shift sleeve and a driver element, which is suitable for engagement of an actuator.

Den vorbekannten Lösungen ist gemein, dass sie entweder hinsichtlich der Bauteilfestigkeit beschränkt sind, wenn nämlich Kunststoff zum Einsatz kommt, oder dass der Fertigungs- und Montageaufwand relativ hoch ist.The previously known solutions have in common that they are either limited in terms of component strength, namely when plastic is used, or that the manufacturing and assembly costs are relatively high.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Betätigungsvorrichtung für eine Schaltmuffe der eingangs genannten Art so fortzubilden, dass die genannten Nachteile vermieden werden. Die Vorrichtung soll also sowohl eine hohe Bauteilfestigkeit aufweisen als auch in besonders wirtschaftlicher Weise herstellbar sein.The present invention is therefore based on the object, an actuating device for a shift sleeve of the type mentioned in such a way that the mentioned disadvantages are avoided. The device should thus both have a high component strength and be produced in a particularly economical manner.
Die Lös u n g dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass die Schaltgabel, das mindestens eine Führungselement und das Mitnehmerelement der Betätigungsvorrichtung einteilig und aus einem einzigen Blechteil ausgebildet sind.The solu tion of this object by the invention is characterized in that the shift fork, the at least one guide element and the driver element of the actuating device are formed integrally and from a single sheet metal part.
Der Herstellaufwand wird hierdurch wesentlich reduziert, so dass eine besonders wirtschaftliche Produktion der Vorrichtung möglich wird. Durch den einteiligen Verbund ergibt sich auch eine hohe Bauteilsteifigkeit. Da ein metallisches Blech als Grundmaterial der Vorrichtung zum Einsatz kommt, ist die Bauteilfestigkeit gleichermaßen sehr hoch.The manufacturing effort is thereby significantly reduced, so that a particularly economical production of the device is possible. The one-piece composite also results in a high component rigidity. Since a metal sheet is used as the base material of the device, the component strength is likewise very high.
Das Blechteil ist im Ausgangszustand vorzugsweise eben ausgebildet und weist eine im wesentlichen konstante Blechdicke auf.The sheet metal part is preferably flat in the initial state and has a substantially constant sheet thickness.
Eine besonders wirtschaftliche Herstellung der Vorrichtung wird möglich, wenn einer der Arme der Schaltgabel durch einen aus dem Blechteil ausgestanzten und aus der Ebene des Blechteils herausgebogenen Abschnitt gebildet wird.A particularly economical manufacture of the device is possible if one of the arms of the shift fork is formed by a punched out of the sheet metal part and bent out of the plane of the sheet metal part.
Mindestens ein Arm kann sich von der Basis der Schaltgabel zum Ende des Arms verjüngen; die Verjüngung erfolgt dabei bevorzugt in Achsrichtung der Schaltmuffe.At least one arm may taper from the base of the shift fork to the end of the arm; the taper is preferably carried out in the axial direction of the shift sleeve.
Eine besonders einfache Herstellung des einen Arms wird erreicht, wenn dieser durch zweimaliges Abbiegen des Blechteils gegenüber der Basis der Schaltgabel gebildet ist. Der von der Basis der Schaltgabel entfernte Teil des Arms kann dabei im wesentlichen rechtwinkelig zur Basis angeordnet sein. Entsprechend kann der andere Arm der Schaltgabel durch einmaliges Abbiegen des Blechteils gegenüber der Basis der Schaltgabel gebildet werden; auch dieser Arm kann im wesentlichen rechtwinkelig zur Basis angeordnet sein.A particularly simple production of the one arm is achieved if this is formed by twice bending the sheet metal part relative to the base of the shift fork. The remote from the base of the shift fork part of the arm can be arranged substantially perpendicular to the base. Accordingly, the other arm of the shift fork can be formed by a single turn of the sheet metal part relative to the base of the shift fork; Also this arm can be arranged substantially perpendicular to the base.
Eine Weiterbildung sieht vor, dass zwei in Achsrichtung der Schaltmuffe und in entgegengesetzte Richtungen weisende Führungselemente aus dem Blechteil ausgebildet sind. Diese können als sich in Achsrichtung erstreckende Stifte ausgebildet sein; die Stifte können eine im Querschnitt rechteckige oder quadratische Form aufweisen.A further development provides that two guide elements pointing in the axial direction of the shift sleeve and in opposite directions are formed from the sheet metal part. These may be formed as extending in the axial direction pins; the pins may have a rectangular or square cross-sectional shape.
Die Betätigungsvorrichtung kommt bevorzugt bei Kraftfahrzeug-Schaltgetrieben zum Einsatz.The actuating device is preferably used in motor vehicle manual transmissions.
In vorteilhafter Weise werden durch den Erfindungsvorschlag Bauteile eingespart, d. h. die Betätigungsvorrichtung kann aus sehr wenigen einzelnen Bauteilen hergestellt werden.Advantageously, components are saved by the proposed invention, d. H. The actuator can be made of very few individual components.
Auch die Fügeprozesse bei der Herstellung der Vorrichtung werden reduziert bzw. sie fallen vollständig weg. Es ist namentlich kein Schweißen oder Verprägen erforderlich, um die Vorrichtung herzustellen.Also, the joining processes in the manufacture of the device are reduced or they fall completely away. In particular, no welding or embossing is required to make the device.
Dadurch ergibt sich auch, dass es zu keiner Beeinträchtigung der Vorrichtung durch Wärmeeinfluss kommt.This also results in that there is no impairment of the device due to the influence of heat.
Die komplette Herstellung der Betätigungsvorrichtung ist in einer einzigen Werkzeugmaschine (Bearbeitungszentrum) möglich, wenn diese mit entsprechenden Werkzeugen ausgestattet ist.The complete manufacturing of the actuator is possible in a single machine tool (machining center), if it is equipped with appropriate tools.
Durch die Integration aller relevanten Funktionen in das einstückige Bauteil wird die Toleranzkette reduziert, so dass eine höhere Bauteilgenauigkeit mit geringerem Aufwand erzielbar ist. Ein Aneinanderfügen unterschiedlicher Bauteile entfällt.By integrating all relevant functions in the one-piece component, the tolerance chain is reduced, so that a higher component accuracy can be achieved with less effort. A joining together of different components is eliminated.
Von Vorteil ist ferner, dass deshalb eine verbesserte Funktion der Vorrichtung zu erwarten ist, da der Kraftverlauf im Bauteil aufgrund einer höheren Homogenität des Teils verbessert ist. Weiterhin sind im Vergleich zu den vorbekannten Lösungen geringere Verformungen zu erwarten, da die Vorrichtung stabiler bzw. fester ausgestaltet werden kann. Es ergeben sich weiterhin geringere Spannungsspitzen im Material.Another advantage is that therefore an improved function of the device is to be expected, since the force curve is improved in the component due to a higher homogeneity of the part. Furthermore, lower deformations are to be expected in comparison with the previously known solutions, since the device can be made more stable or stronger. There are still lower voltage spikes in the material.
Die Bauteilvielfalt kann durch den Erfindungsvorschlag reduziert werden, so dass sich auch die Logistik einfacher gestaltet.The variety of components can be reduced by the proposed invention, so that the logistics are easier.
Die Kostenreduzierungen ergeben sich daher nicht nur durch die einfachere Fertigungsweise der Betätigungsvorrichtung.The cost reductions are therefore not only due to the simpler way of manufacturing the actuator.

In den Figuren ist eine Betätigungsvorrichtung 1 zu sehen, mit der eine Schaltmuffe 2 betätigt werden kann, d. h. mit der die Schaltmuffe 2 in Achsrichtung A verschoben werden kann, um einen Schaltvorgang in einem Zahnräderwechselgetriebe in bekannter Weise durchzuführen.In the figures, an
Ein funktionswesentlicher Teil der Betätigungsvorrichtung 1 ist zunächst die Schaltgabel 5, die zwei Arme 3 und 4 aufweist, die in eine Ringnut 12 am Umfang der Schaltmuffe 2 eingreifen. Damit ist eine axiale Verschiebung der Schaltmuffe 2 bei entsprechender Bewegung der Schaltgabel 5 möglich.A functionally essential part of the
Ferner hat die Betätigungsvorrichtung 1 mindestens ein Führungselement, das im Ausführungsbeispiel durch die beiden Elemente 5 und 6 gebildet wird. Mit diesen stiftförmigen Elementen 5, 6 wird die Betätigungsvorrichtung 1 in einem nicht dargestellten Getriebegehäuse gelagert und geführt.Furthermore, the
Ein weiterer wesentlicher Teil der Betätigungsvorrichtung 1 ist das Mitnehmerelement 8, das mit einem Betätigungsorgan zusammenwirken kann. Bei dem Betätigungsorgan kann es sich um einen Teil eines Schaltgestänges handeln oder um einen andersartig ausgebildeten Aktuator, mit dem eine gesteuerte Bewegung in Achsrichtung A erzeugt werden kann. Das Mitnehmerelement 8 nimmt also die von dem Betätigungsorgan erzeugte Schaltkraft auf.Another essential part of the
Alle drei funktionswesentlichen Teile, also die Schaltgabel 5 mit ihren beiden Armen 3, 4, das Führungselement 6, 7 und das Mitnehmerelement 8 sind einteilig bzw. einstückig ausgebildet. Die Betätigungsvorrichtung 1 ist nämlich aus einem ebenen Blech geformt, das im Ausgangszustand, also vor dem Beginn der Blechumformung, eine ebene Kontur hat und eine konstante Blechdicke d aufweist.All three functionally essential parts, ie the
Aus dem ebenen Blech wird durch Abkanten, Stanzen, Biegen und ggf. Tiefziehen das Bauteil spanlos hergestellt, d. h. so umgeformt, wie es in den Figuren zu sehen ist. Hierzu wird zunächst ein Teil aus einer Blechtafel so ausgestanzt, dass sich die benötigte abgewickelte Kontur der Betätigungsvorrichtung ergibt. Dieses ausgestanzte Teil wird dann weiter spanlos umgeformt.From the flat sheet is produced without cutting by bending, punching, bending and optionally deep drawing, d. H. reshaped as seen in the figures. For this purpose, a part of a metal sheet is first punched so that the required developed contour of the actuator results. This punched-out part is then further formed without cutting.
Besonders vorteilhaft ist die Ausgestaltung des einen Arms 4 der Schaltgabel 5. Die Schaltgabel 5 weist eine Basis 9 auf, die als Referenzfläche betrachtet werden kann. Aus dem Bereich der Basis 9 sowie des angrenzenden Teils des anderen Arms 3 wird eine streifenförmige Kontur 13, s. Fig. 2, teilweise ausgestanzt, wobei jedoch das eine Ende dieser Kontur 13 stoffschlüssig mit der Basis 9 verbunden bleibt. Die aus dem Material der Basis 9 gelöste Zunge wird dann aus der Ebene der Basis 9 herausgebogen, und zwar - wie es am besten in Fig. 1 zu sehen ist - etwa rechtwinkelig zur Basis 9. Hierdurch wird der Arm 4 ausgebildet.The embodiment of the one
Der andere Arm 3 der Schaltgabel 5 besteht aus zwei Abschnitten 3' und 3", die beide jeweils im wesentlichen gerade ausgebildet sind, jedoch jeweils um einen Winkel relativ zueinander abgekantet sind. So ist der Teil 3' des Arms 3 gegenüber der Basis 9 abgewinkelt (s. Fig. 1); ebenfalls ist der Teil 3" des Arms 3 relativ zum Teil 3' des Arms 3 abgewinkelt.The
Die Enden 10 und 11 der beiden Arme 3 und 4 sind dabei im wesentlichen rechtwinkelig zur Basis 9 angeordnet, so dass sich ein Schaltmaul ergibt, das in die Ringnut 12 der Schaltmuffe 2 eingreift.The ends 10 and 11 of the two
Ferner ist vorgesehen, dass sich insbesondere der Arm 3 der Schaltgabel von der Basis 9 aus in Richtung des Endes 10 des Arms 3 verjüngt, wie es gut in Fig. 3 gesehen werden kann.It is further provided that in particular the
